Abstract

This paper was to study the stability of three oils during vacuum low-temperature frying of carrot slices and to evaluate frying oil quality. The effect of the frying time on acid value, peroxide value and carbonyl value was studied and the correlation between frying time and these values was analyzed. Results showed that palm oil and lard possessed greater thermal stability than soybean oil. And acid value, peroxide value and carbonyl value all showed good correlations with frying time.
